== ASIO leadership ==
[[David Sadleir]] succeeded [[John Moten]] as director-general of the [[Australian Security Intelligence Organisation]] in 1992. The agency’s published chronology records his term as 27 April 1992 to 10 October 1996. [[Dennis Richardson]] took over on 11 October 1996.<ref name="ASIOList" />

== Succession and historical setting ==
[[David Sadleir]]’s tenure followed the end of the Cold War and the earlier relocation of the [[Australian Security Intelligence Organisation]] to Canberra. [[John Blaxland]]’s account of the preceding period describes the relocation as a significant change in the organisation’s relationship to central government; his third volume of the official history ends in 1989, before Sadleir’s appointment.<ref name="ASIOList" /><ref name="BlaxlandSpeech">John Blaxland, [https://thesydneyinstitute.com.au/blog/australias-secret-cold-war-2/ Australia’s Secret Cold War], The Sydney Institute, speech delivered 5 December 2016, accessed 8 November 2026.</ref>
